| Research Abstract |
We performed model simulations of FePt isolated grains, for estimating recording process in thermally assisted recording with near field optical head. We could verify the magnetization of one FePt grain was reversed. FePt or FeCuPt particles were fabricated by rapid thermal annealing method on two kinds of nano-structured substrates. Nano-Dent Array substrate with periodicity of 14 nm was prepared by the polymer micelles technique. The other is Self-Assembled spherical small Silica Particles with diameter of 18 nm which was fabricated by the dip coating method. By utilizing those substrates, average diameter of FeCuPt particles was successfully reduced and areal density of particles was drastically increased.
